Sweet Seeds A couple questions for anyone who has grown some of the fast versions

[Animatey]

Hey yall,

I am fairly sold on sweet seeds, especially the fast version line.

I have all of the fast version seeds on hand that finish in 7 weeks or less.

I have a couple questions however...

1. Which is the shortest in height of the Fast Versions? I saw in the grand prix posted here that no sweet specials went over 65cm which is pretty short... My grow spaces are generally pretty low.
2. Is topping fast versions an ok way to train them? It seems like most of them have a main central kola, and I wonder how a plant like that would react to having the main stem pruned?

Thanks anyone who happens to see/read ;D !
